Abstract
The object of this study was to obtain data on the radial variation of gas- and liquid-phase mass flux profiles in two-phase upflow in vertical pipelines. Experimental data were obtained on the radial gas-liquid flux, impact pressure, and linear liquid-phase velocity profiles for superficial gas- and liquid-phase velocities ranging from 20 to 125 ft/s and from 5 to 15 ft/s, respectively. Studies were made on 1-in, 4-in, and 8·4-in vertical pipelines and in a 1-in i.d. by 8·4-in o.d. vertical annular flow pipeline. Gas-liquid systems studied were air-water, air-aqueous glycerol, and air-tetrabromoethane.
In Part 2 time-averaged radial liquid hold-up and linear-phase velocities were estimated from radial mass flux and impact pressure data. Estimates were also made on the magnitude, frequency, and velocity of the flow disturbances. Empirical correlations for mean liquid hold-up and pressure drop were developed from experimental data.
